10 Claims.

This invention relates to a method or process for manufacturing beaded cord that involves a substantially continuous process at relatively 7 high speed and that produces a product almost as strong and durable as a bead chain but at a much cheaper cost. The method further includes the seasoning of the stock and then finishing the same with the desired color or hue or with a metallic coating or the like.

In accordance with this invention, a flexible string-like member which may be a cord, wire, chain or rope, but preferably a cord, is fed in a horizontal path for the application of spots of glue in properly spaced relation, the drying of the glue spots, the application of suitable composition to the glue spots, finishing the beads thus formed under hot temperature and passing the same thru a quick freezing chamber, then dipping the same in a prime coating solution to close the pores or crevices and preserving the shape as raw material stock for a period of seasoning, after which the beaded cord may be colored or provided with a metallic finishing coating as desired.

The invention comprises the .novel process hereinafter described and more particularly pointed out and defined in the appended claims.

In the accompanying drawing which illustrates an apparatus for carrying out this invention and in which similar reference numerals refer to similar features in'the different views:

Fig. 1 is a side elevational view shown somewhat in diagrammatic form of an apparatus for carrying out this invention.

Fig. 2 is a sectional view taken upon the line 1.

2-2 of Fig. 1 looking in the direction of the arrows and showing parts in elevation.

Fig. 3 is a sectional view taken substantially upon the line 33 of Fig. 1 looking in the direction of the arrows.

Fig. 4 is a diagrammatic view of a coloring unit forming a part of the apparatus.

In referring to the drawing, there is shown in Fig. 1, a reel or drum 5 which supports a supply of cord upon which it is desired to place beads.- This cord whichis designated 6 is passed between a pair of guide rolls 1-! supported on a bracket 8 rising from a glue tank 9. A rotatable shaft I is supported in the wall of the glue tank and this shaft carries a gluing arm I I within the tank. Rotation of the shaft will rotate the arm. H causing the same to dip into the glue in the tank and deposit such glue as adheres to its tip against the cord when the arm rises sufliciently.

As the cord travels substantially continuously, 56

while the arm ll strikes the cord intermittently the glue spots which are represented by the reference l2 will occur in uniform spaced relation.

The glue spots [2 which are made by a fast drying glue are subjected to the drying influence of a rotary fan l3 which is conveniently positioned adjacent the path of travel of the cord for the purpose of expediting the drying of the glue spots. The cord next .passes between a pair of co-operating rolls l4 and I5 which are provided respectively with semi-spherical cavities Ma and |5a in their peripheries so spaced in each -roll that a cavity in one will register with a cavity in the other roll at the point of tangency of the rolls, that is at the point where they come closest together. With reference to Fig. 3, it will be noted that the rolls l4 and I5 are provided respectively with off-set rim portions Nb and Hi l) in which the cavities are formed.

Contacting the inner surface of each off-set rim of the rolls, there is an air inlet member l6 which is provided with an air inlet duct I! to which air under pressure may be periodically supplied from an air hose l8. An air passage l9 extends from each duct ll to the off-set rim Mb or l5b for periodic registration with air ducts 20 in the off-set rims which ducts communicate with the cavities therein. The members It are provided with curved surfaces to correspond with the inner surfaces of the rims and they are positioned centrically of the cominon. diameter of the rolls that passes thru the point of tangency of the rolls. As a result, when a pair of cavities come into registration, their air ducts 20 will register with the air ducts 19 whereby air under pressure may be supplied or forced into the cavities to release the half beads as will later more fully appear.

A suitable composition in the form of a viscous, plastic and somewhat liquid material is adapted to be supplied to the cavities in the rolls l4 and 15. As a matter of illustration, there is shown a tank 2| adjacent the roll M for containing the plastic composition. A pair of co-operating material transfer rolls 22, one engaging roll I4, are supported by the tank 2| for transferring the material therefrom to the cavities in the roll l4. For this purpose, the rolls 22.may be brush rolls or the like or have suitable conveying surfaces. They may be rotated, by any suitable means.

At the bottom of the roll I5, there is a second tank 23 for containing a similar plastic composition material which is adapted to be supplied to the cavities l5a in the roll l5 by a rotatable between a pair of semi-cylindrical rolls 2! which have threaded peripheries upon their arcuate surfacesofsuchapitchastocauseaspeedequal to'thespeedoftraveloftbecord. Asthe beadedcordpassesbetweenthesehalf moonrolls,any

flnsthatmay havebeen formed during the application of the beads are removed and the beads are more or less burnished. These rolls are adapted to be heated by the gas jets 28, one adjacent each roll. These rolls might be termed finishing rolls for the beads.

The beaded cord or string-like beaded member then passes thru a freezing or refrigeration tank 1! containing a quick freezing mixture or chamber.

From the refrigerating tank 23, the beaded cord passes over a guide roll 3| and into a dipping ta'nk 3i containing a prime coating solution which closes the pores of the beads and preserves the shape. The beaded cord then passes from the tank over another guide roll 32 and onto a reel or drum 33 for a period of seasoning. This product may be termed the raw stock which, after seasoning, is ready for finishing according to desired specifications.

After a suitable period of seasoning and when itisdesiredtoutilizeordisposeofpartorallof the raw stock, it may be finished as to color or coating by passing the same thru the finishing or coating mechanism shown in 4 which will have been supplied with the proper coloring solution or spray. To accomplish this, the beaded cord or string-like member from the storage roll beaded flexible member which consists in sup-.

33 is passed over a guide roll 34 supported above the dipping tank 35 from which roll, the beadedbetween the tanks :5 and n which is adapted to remain idle when desired, but which may be used for giving the beaded cord a metallic finish when desired; in such an event, the tanks need not be utilized. For such a purpose, the

I beaded cord may be passed down between the two parts 38 of the spraying device thru the guide rolls 3! and 33; then up over a guide roll and into the tank ll.

From the dipping tank H, the beaded cord is led over a guide roll 3 and \mto a second storage roll 44. For drying purposes, a rotary fan may be positioned adjacent the beaded cord between the tank I and the roll 44.

Incaseswhereitisdesiredtoimpart to the beaded cord a metallic finish, the tank 35 may be provided with a suitable paint for giving the beaded cord a second coating and the spray 38 turned on for imparting the metallic finish to the beads. The metallic coated beaded cord is acted upon by a rotary buffer wheel I as it leaves the guide roll 3! and proceeds to the dipping tank ll where suitable driving means maybe used.

While the driving mechanisms for the different elements are not illustrated in the drawing,

I am aware thatchangesmaybemadeinthis process and the steps thereof without departing from the principles of this invention, so I do not propose limiting the patent granted thereon otherwise than necessitated by the appended claims.

I claim as my invention: 7 1. The herein described method of making a porting, guiding and moving a string-like member in a predetermined path, applying glue spots in spaced relation to said member, partially drying said spots,then forming semi-spherical bead members and simultaneously pressing them from opposite directions upon a glue spot to form a bead, then properly shaping and bumishing said bead imder heating temperature and then cooling and dipping the same. J

2. The herein described method of applying beads to a string-like member which consists in supporting, guiding and moving a string-like member in a predetermined path, app yi glue spots in spaced relation to said member, subjecting aid glue spots to air currents for partially drying the same, forming a pair of semi-spherical bead members, simultaneously pressing the same from oppo ite directions on a glue spot, then burnishing said bead and subjecting the same to a freezing temperature.

3. The herein described method of applying beads to a string-like member which consists in continually moving said member in a predetermined path, applying glue spots on said member at one point in said path, subjecting said glue 4. The herein described method of applying.

beads to a string-like member which consists in simultaneously moving said member in a predetermined path, applying glue spots at spaced points to said member at one point in said path, subjecting said glue spots to air currents at another point in said path, forming semi-spherical bead members and pressing them in pairs-from opposite directions upon said string-like member over a glue spot at another point in said path, bumishing the formed beads under heating temperature at another point in said path and then cooling the sfring-like bead member thus formed.

5. The herein described method ofmaking a beaded cord which consists in moving acord in any a flattened wedge-shaped knife 'edged tip 52 which is adapted to engage in a notch 53 of a connecting'member 54. The connecting member 54 is adapted to connect a' cutter blade 55 to the arm The cutter blade 55 is of a semi circular cross-section and is slotted to provide teeth 55 adapted to cooperate with the correspending teeth on the comb blade 1. In order To provide this kind of mounting with un-.

yielding driving action in the direction of reciprocation of the cutter blade, I mount the member 54 in the cutter blade so that it may spring toward and away from the teeth of the cutter 'blade but cannot move endwise. of the cutter blade. The cutter blade is provided with two notches 51 and 58 in which are mounted two cars 59 and 60 on the member 54. Slots 6| and 62 are cut in the back edges of the cutter blade adjacent the other end thereof, and ears 63 and 64 are provided on the member 54 for pressing, The ears 53 and '64 are smaller than the slots 6| and 62 so that they in the slots 6| and 62.

may move endwise in the slots. The member 54 is a spring blade and is yieldingly pressed toward the teeth of the cutter blade by the tip of the arm 5|. for a driving connection to reciprocate the cutter blade, and this driving connection is: the same even though the amount the member 54 is pressed toward the teeth 56 may vary in dif-' ferent devices and may vary in the same device due to the wear of the parts. It will be appreciated that if the member 54 is bent'out of astraight line the distance between theears 59 and 60 at one end and the ears 63-and 64 at the other end will change slightly. The straight edge slots 6| and 62 allow for this change in length without allowing any play in the driving connection which is through the notches 51 and 58.

In Fig. 12 a slightly modified form of the member 54 is shown. In this form the notch 53 is provided by bending the member 54 instead of by punching up sections thereof as in the main form. The ears 59 and 60, 63 and 64, are adapted to cooperate with the cutter blade in the same fashion as in the other form.
